To all whom it'm'ay conc rn: I

Be it known that I, CLA ENCE W. Utrz- MAN, a citizen of the United States, 'res1ding at Chicago, in the county of Cock end State of Illinois, ihventedeertein new and useful Improvements in Floor Construct-ioiis, of which the following is a speci fieetion.

This invention relates in general to build- WO OCl'BII eonetruetion wh-iehmust its sembled on each joh t e-ken down efter the concrete or stucco has set, or of substantiell "inverted U-shejp'e with herizente lly pro jee ting'flange's at their ends. The 1n vertcd U4shepe forms were suppottedi1p0n the false work with the fien 'ed ende oi edjacent forms in ontiguous Telati'on to PIO- cluce the heme between the sides of adjacent forms when eencrete wa poured over them. 'U'nlese the :foms are laid with "extreme accuracy the beanie produeed thereby will be irregular Width, and liuithe'i'hiore, when coiicrete is potted to form one beam the forms have e tendency to separate at their sides under the Weight of the coiict'ete,

in the H601 and which Will memeeiej its" and in many instances the forms will be distorted at their line of clii'vg tlii ehetween' the vertical side walls and the horizontal top wells. Afuither lieedve t gesef forms of this character that they een eeIy be laid to produce heems exter icli rrg" iii enedi f rection, wher as it is often to heve the integral heatn's extehd in both directions,

that is, hoth laterally and l'ohgitudinally of the floor structure. i i

My present invention is des gned 'to (were come the weakne ses end e'l jeetieneble features of the fdrinslheretofore employed in producing concrete Home end eenteieeletee the provision at a eenetriietieewhieh will permit the "eeeueete un'iferrh formation i of both transverse lohgithmiinal beams shape, not be subjeet to displacement er Hie:

when "under "the Weight er the do'liei'ete these molds "being of apredetefminetl width en ipf dfiieiem strength to maintain their original shape when the coiic'rete oi stlieco 1s poured into them.

Another object of "my invention is to pie vide supportihg means for the concrete poured loetweeli the vehifil'ls channel memhere, said SUppOPtlTi means being eonstructed to rest upon t 1e 'upper edges of'the flehennel membere and com letely cover the spaces between acljeceiit members.

A further object of my ihvehtio'n is to provide mea s for festeniiig the ceiling hem-d5, to which the plaster of the ufic'lerlyin'gi ceiling is applied, to the concret beams so that the boards may be attached and sec'uTecl in p'lzi-ce Without baring or plugging into the cohci'ete for stucco.

For the purpose of facilitatingan uhderentitling of my invention I have disclosed preferred embodiments thereof in the accompa nying (li'ew'ihgs, to whichfeterence is made i'hlhe following description.

Referring to the drawings, and more per- .tichlerly to Figsfl to thereol', it will be hel ferthe concrete 'bettnis 6 hy ineahs of invei'tect foi'ihs hwinge horizontal flan es;

which abut beneath end eien 'thebehter line e f eeehbeem, Ilhjilbj "chthhl sh'aped memliere deeigneteet by fefetehce e aracter suitable plastic material such as stucco having paper incorporated in its construction. These channel-shaped members are substantially U-shape in cross section and may be made in any size of beam cross section and length desired, and are capable of being sawed or cut to fit into any place where they may be desired. In forming the floor structure these channel members are posia cut out of the side walls of the members 7.

In making a oint the ends of the channels are preferably chamfer'ed off as shown to make a close strong union, and the oint is'secured' together by metal clips 11 bent to embrace both of the intersecting channel members. A corner joint is indicated by reference character 12, the construction of which will be obvious. It will thus be manifest, particularly from Fig. 5, that when the channel members are properly joined and positioned they produce a continuous channel into which concrete or other material may be poured to form integrally united beams. In Fig. 5 I have illustrated a construction which provides for T-joints, cross-joints and L-joints.

Referring again to Fig. 1, after the channel members have been positioned as described the space between members is covered by sheets of plaster board 13, or other material which will form .a permanent part of the floor structure. Metal clips 14, shaped substantially as shown, unite the upper edges of the channel members with the sheets 13. The reinforcing members 15 with which the girders are customarily equipped and which may be of any preferred type, are now. positioned in the channel members whereupon concrete orother plastic material is poured over the entire form produced by the channel mem- ,bers and the covering sheets. The concrete will fill the channel members producing the beams and will flow overthe covering sheets '..-producing the floor properwhich, as will be obvious, is'integrally connected with the concrete.

beams- A finishing surface 16, of any preferred type, may then be applied to the Since the bottom and side walls.

of the channel members are of integral con struction and'since the upper edges of the channel members are braced and supported against lateral displacement by the sheets Where they join 13 it will be obvious that a very strong mold is produced in which beams of exactly the desired dimensions will be formed.

The channel members are thickened. at the lower corners between the upright and bottom walls so that they are strongest at this point where the ordinary forms are usually weakest, and any liability of distortion of the forms by the weight of the poured con crete or other material is thereby eliminated.

In the construction shown in Fig. 1, I attach to the sides of the channel members 7 adjacent their lower corners, metal brackets 17 which. are secured to the channel members by nails 18 before the concrete is poured, the nails being preferably of sufficient length to extend into the concrete or other material and be anchored therein when the beam is formed. These brackets are adapted to support ceiling boards 19, preferably of plaster board, which may be anchored in position by nails 21. The plaster 22 of the underlying ceiling may then be applied to the boards and the bottoms of the channel members 7, producing a finished ceiling underneath.

In Fig. 2 I have shown another form of the invention in which the channel members 8 are slightly shallower than the channel members 7 shown in Fig. 1. Instead of eniploying sheets of plaster board 13 as in the formshown in Fig. 1 I employ covering slabs or plates 23 formed of corrugated metal or the like, bent as shown to provide a thickened portion 24: at the juncture of the beam with the floor slab. This figure shows the lower edges of the plates as provided with one form of spaced clips or fingers 25 and 26 which embrace opposite sides of the upper edges of the channel members and securely lock the plates 23 to the channel members. The plates are therefore supported by and securely attached to the spaced channel members to provide a rigid mold for the concrete or stucco. When the construction embodies a two-way structure, as shown in Fig. 5, the plates 23 are shaped to cover an opening bounded by four of the channel members, and each of the four edges of the plate is provided with the holding fingers 25 and 26.

In this form of the invention I provide the channel members 8 with fastening de vices 27 which are inserted through slits in the bottom wall in the channel member and are provided at their upper ends with anchors 28 shaped as shown in Fig. 2. The fastening devices are provided near their upper ends with openings or depressions and the anchors are provided with correspondingly positioned inwardly projecting extens1ons which enter the openings and securely lock the anchors to the fastening devices.

. WJhen the beam is poured the fastening devlces are securely anchored in the concrete.

The lower ends of the fastening devices are shaped substantially as shown to provide slots 29, the lower wall of the channel memher being provided with depressions 31 to receive the metal which forms the slots. Substantially U-sha-ped clips 32 are inserted into the slots 29 and the plaster block or other ceiling blocks 33 are provided with slots 34 at their ends adapted to receive the lower horizontally projecting portions of the clips by which the blocks are supported in position. The fastening devices 27 are positioned before the concrete is poured, as previously explained, and after the false Work has been taken down the plaster blocks may be secured in position by means of tlfe clips 32 as will be readily understood.

In Fig. 3 I have illustrated a slightly modified construction in which the anchor consists of a nail or spike 35 inserted through apertures in the upper end of the fastening device 27 The clips 36 in this instance are of sufficient length to embrace the slabs of plaster board 37 instead of being inserted in slots in the end thereof as it is disclosed in Fig. 2. With either form of the invention the plaster board or other ceiling material may be readily secured in position after the false work or centering has been taken down.

From the foregoing it should be apparent that I have provided a floor construction which is strong and rigid, which will insure that the beams will be of the required dimensions so that the exact amount of concrete or other material necessary can be accurately figured in advance, and which provides means for quickly and easily attaching the ceiling boards to the beams without borlng or plugging into the concrete. If it 3 should be desirable to employ metal or other in two directions throughout the floor area,

said members being securely fastened together at their points of intersection so as to produce continuous and intersecting channels, means for covering the spaces between said members, plastic material disposed over said covering means and filling said channel members to produce a continuous floor structure having integral beams extending longitudinally and transversely in the floor, fastening devices carried by said channel members ceiling boards or blocks disposed beneath the members, and clips detachably engageable with said fastening devices for holding said ceiling boards or blocks in position.
